Definitions

  • the present invention relates to a door lock, and, more particularly, to a locking door handle set having a supplemental child-resistant lock.
  • a typical door handle set includes a latch bolt assembly and a latch bolt lock.
  • the interior handle often includes an axial turn button or push button on the interior side of the door to operate the latch bolt lock.
  • the latch bolt assembly may be unlocked from the inside of the door by simply rotating the interior door lever/knob. It has been observed that a child, such as a toddler, may have the dexterity to actuate the interior lock button or rotate the interior door lever/knob, thus unlocking the door and permitting the child to leave the room unbeknownst to the supervising adult, such as the child' s parent.
  • GB 1279989 Another type of lock is disclosed in GB 1279989, wherein the door lock has a vertical slider member that is located in plain view and is movable up and down to selectively engage a notch in a disc that cooperates with a latch part.
  • the slider member being in plain view to a child of toddler size, the child may still be able to easily unlock the door.
  • the present invention provides a door handle set having a child-resistant lock that may be used to supplement the primary lock of the door handle set.
  • the invention in one form is directed to a door handle set that includes a handle assembly having a primary lock and having a handle rotatable about a primary rotational axis.
  • a latch bolt assembly has a latch bolt.
  • the latch bolt assembly is operatively coupled to the handle assembly, wherein a rotation of the handle results in a linear translation of the latch bolt.
  • a supplemental lock has a second axis parallel to, and spaced apart from, the primary rotational axis.
  • the supplemental lock has an actuator that is operable relative to the second axis.
  • the supplemental lock is configured to selectively block the rotation of the handle regardless of the locking state of the primary lock.
  • the invention in another form is directed to a door handle set that includes a handle assembly having a chassis, a primary lock, and a handle rotatably coupled to the chassis.
  • the handle is rotatable about a primary rotational axis.
  • the primary lock is arranged along the primary rotational axis.
  • a latch bolt assembly has a latch bolt.
  • the latch bolt assembly is operatively coupled to the handle assembly, wherein a rotation of the handle results in a linear translation of the latch bolt.
  • a supplemental lock has a translation axis that is substantially orthogonal to the primary rotational axis.
  • the supplemental lock has an actuator that is operable relative to the translation axis, wherein the supplemental lock is configured to selectively block the rotation of the handle regardless of the locking state of the primary lock.
  • An advantage of the present invention is that the supplemental (child-resistant) lock may be operated easily by an adult from inside and/or outside of the door, but a child may not be able to easily understand and operate the lock, so as to prevent the child from going outside unsupervised while the supervising adult, e.g., parents and/or family member, is unaware.
  • supplemental (child-resistant) lock operates as a "safe pass mechanism", which prevents the door from being opened by rotating the door lever directly to unlock the primary lock.
  • Yet another advantage in one embodiment, is that an adult may lock and unlock the supplemental lock from inside or outside of the door, but the supplemental lock does not affect the original function of the primary door lock.
  • Yet another advantage is that in an emergency situation, an adult can overcome the secondary locking provided by the supplemental (child-resistant) lock by forcefully and directly rotating the door lever/knob.
  • Fig. 1 is a perspective view of a handle set having a supplemental lock, in accordance with an embodiment of the present invention.
  • Fig. 2 is a side view of the handle set of Fig. 1 that shows a portion of a supplemental lock, and depicts a primary lock and key cylinder by dashed lines.

Interior handle 84 is rotatably coupled to an interior chassis 80-1, and is positioned to rotate about a primary rotational axis 86. Interior handle 84 is coupled to latch spindle 28 for rotation in unison therewith. A rotation of interior handle 84 results in a linear translation of latch bolt 18-2 via a corresponding rotation of latch spindle 28.
  • Supplemental lock 82 includes an interior actuator 88, which is in the form of a slider, and which is configured to translate linearly along a secondary translation axis 90.
  • Interior actuator 88 is slidably coupled to interior chassis 80-1 and/or interior escutcheon 80-2 for linear translation along the secondary translation axis.
  • Secondary translation axis 90 is substantially orthogonal to primary rotational axis 86, and is positioned to intersect primary rotational axis 86.
  • Interior actuator 88 includes a projecting portion 88-1 that translates along secondary translation axis 90, and projects downwardly through a slot in interior escutcheon 80-2.
  • Projecting portion 88-1 includes an engagement portion 88-2 and a detent portion 88-3.
  • Engagement portion 88-2 extends inwardly away from interior handle 84, and may be oriented to extend parallel to primary rotational axis 86, so as to selectively engage radially inwardly facing notch 34-3 of rotation plate 34 when projecting portion 88-1 is moved downwardly to the blocking position.
  • Projecting portion 88-1 may be formed as an L-shaped wire structure having a vertical portion and a horizontal portion, wherein the engagement portion 88-2 is the horizontal portion and extends substantially parallel to primary rotational axis 86.
  • Detent portion 88-3 of interior actuator 88 is in the form of at least one offset in projecting portion 88-1.
  • the offset forms a bump that axially contacts a side wall of interior chassis 80-1 when projecting portion 88-1 is translated downwardly toward the blocking position.
  • the bump may be in the form of a V-bend in the vertical portion of the wire structure of projecting portion 88-1, with the apex of the bump facing in a direction toward interior chassis 80-1.
  • Fig. 9 shows supplemental lock 82 in a non-blocking positon, wherein interior actuator 88 and projecting portion 88-1 are raised along secondary translation axis 90, so as to disengage engagement portion 88-2 from radially inwardly facing notch 34-3 of rotation plate 34, and with detent portion 88-3 contacting an upper edge of interior chassis 80-1.
  • projecting portion 88-1 is in a non-deflected, e.g., vertical, position.
  • Fig. 10 shows supplemental lock 82 in a blocking positon, wherein interior actuator 88 and projecting portion 88-1 are lowered along secondary translation axis 90, such that engagement portion 88-2 is engaged with radially inwardly facing notch 34-3 of rotation plate 34, and with the apex of the bump of projecting portion 88-1 contacting a side wall of interior chassis 80-1 to apply a lateral force against the side wall of interior chassis 80-1.
  • projecting portion 88-1 deflects laterally due to the engagement of the bump with the side wall of the interior chassis 80-1 to generate the lateral force, with the deflection being in an opposite direction to the direction of the lateral force.
  • the terms “parallel” and “orthogonal” are intended to include slight variations associated with normal manufacturing tolerances, and unless otherwise stated, includes a variation of plus or minus 0.5 degrees.
  • the term “substantially horizontal” means a range of horizontal, plus or minus three degrees.
  • the term “substantially parallel” means a range of parallel, plus or minus three degrees.
  • the term “substantially orthogonal” means a range of orthogonal, plus or minus three degrees.

Abstract

L'invention concerne un ensemble poignée de porte qui comprend un ensemble poignée comportant un verrou primaire et comportant une poignée pouvant tourner autour d'un axe de rotation primaire. Un ensemble pêne demi-tour possède un pêne demi-tour. L'ensemble pêne demi-tour est accouplé fonctionnellement à l'ensemble poignée, une rotation de la poignée entraînant une translation linéaire du pêne demi-tour. Un verrou supplémentaire présente un second axe parallèle à l'axe de rotation primaire et est espacé de celui-ci. Le verrou supplémentaire comprend un actionneur qui peut être actionné par rapport au second axe. Le verrou supplémentaire est conçu pour bloquer sélectivement la rotation de la poignée indépendamment de l'état de verrouillage du verrou primaire.
